I'm Barath, a React Native engineer with 2+ years of experience building and shipping production mobile apps. I sole-architected a fintech app with 200K+ active users across iOS, Android, and Huawei AppGallery — handling everything from Apple Pay native modules and biometric auth to AES encryption and jailbreak detection. I write about real problems I've faced in production — not tutorial-level stuff. If you're building serious React Native apps, you'll find something useful here.
